This convoxity of the plates new nothe anv greater than what is not-ossary to ouahlo thciu to con tain thoarms lwtwt-on thotn.

'vlho four arms aro inserted into the hub, one pair in advance of thoothor so that thoir openings into tho hollow shaft shall i not ho an thosaluttt'ansrorso sortiou. This is dono for tho pnrposo of omnmanding thoadmission of stoma iuto thom. as it is intended to pass into ouo paironly at a time.

In describing this machine I have included many parts of which I donotpretend to be the inventor. and have introduced them merely to showtheir t't'ttmtcliull with those pnt'ts which I do elnini. which are thetwo following:

I chihn 1. The manner of reversing the motion by means of a pistonfitted into the hollow shaft. and covering one half of the openings intothe arms, and capable of being shifted at pletmnre.

2. I nlso claim the manner of uniting the t-nni'ex plates to the huh.and to the cast metal or other plates which pass over the shaft byallowing the former to be received on to. and supported by n rebate nueach end of the ha i, and by riveting the outer edges of the latterthrou h the inner edges of the convex plates. and eying them to theshaft.
